Clockwork Bart was a quick figure to create, which leads me to wonder why I hadn't made him before. I did, however, make another version of this figure from scratch. (See One-of-a-Kind sculptures). This figure was made from the classic Bart. Magic Sculpt putty was used for his jock, sleeves and boots. Plastic "Gymp" was used for his straps. "Gymp", for all you out there that don't know, is a flat, colored, plastic string most commonly used to make bracelets at arts and craft during camp. It makes for great belts & straps.
